We want to achieve the result that will be satisfactory for both parties, we are perfectionists in this matter.

A good example of our skill and professionalism is our pleasant business relationship with HG. Once we engaged into a discussion, we both understood that our cooperation will be mutually beneficial. The task was to finish the development of the application for taking orders online. Delving into someone else's code is often quite a challenge but we managed to complete the app with success. It was so efficient that HG didn't had any doubts who will be his app development company for the second project. This was very thrilling for us. Now we are involved in devlopment of 2 more projects and we do our best to make our clients happy. Please check the HG Order app, HG webshop, HG Sales app II and HG Order Portal for more information. And of course the best testimonial for our work is reflected in his reference.

Also we want to share the agreeable cooperation with RIVM - Ministry of Health Welfare and Sport. Our first project iStrategy app was aimed to support a new IT program policy. We managed to do it in an attractive and dynamic way. The second project was more challenging - an app that informs users about the tick bite danger - Tick Bite app. It had a lot of success among users and in media. We were very proud that the app that we made triggered so much interest in users. RIVM is one of our loyal customers and we are happy to have them.

Testimonials from our clients


ING Bank

Stephan Swerissen, Formula Manager Sparen en Beleggen

"We would like to emphasize:

  • Young, enthusiastic, technical and professional employees
  • Quick feedback + Good communication via phone / email 
  • Good at executing a concrete idea"

De Lotto

Fiona Mirrer, Coordinator Marketing Communication

"For our most popular and best-known lottery scratch-card, December Calendar, we came up with the idea to develop a fun game that you can play both on the PC and on your phone. For this, we started looking for a multimedia partner and found DTT. Despite the short timetable, DTT has made a super game: the December Calendar game. This game, starring the penguins from the December Calendar 2014  lottery scratchcards, is based on an existing game and is intended as a free fun bonus. You can't win (money) prizes, but you can get the highest score! Communication was smooth, clear and fast and we could always turn to DTT if we had questions. DTT also thought actively with us on how we could generate more downloads and gave us good advice where necessary. In short, DTT has been an excellent partner. We will certainly continue working with DTT in future."
